Patented Oct. 9, 1906.

Application filed March 28,1905. Renewed May 9, 1906. Serial No. 315,892.

To all whom it may concern.-

Beit known that I, FRED A. WHITMORE, a citizen of the United States, residing at Philadelphia,- in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Tapestry- Setting Machines, of which the following is 'a specification.

My invention relates to tapestry-setting frame-driving mechanism, and more particularly to improvements in a cone-driving and speed-regulating mechanism for a tapestrysetting frame for winding on abeam the printed yarn.

The object of my invention is to improve upon the construction of the cone-driving and speed-regulating mechanism for a tapestry-setting frame as ordinarily made.

-In my improvements I have one of the two cones of the cone-driving mechanism fast on a rotary shaft having stationary bearings, and I have the other cone, fast on a shaft having bearings on a swinging or pivotally-supported frame, and I provide means for moving said frame and cone to carry the belt encircling the cone on said frame into and rlolit e belt between the cones is automatically shifted, and thespeed of the cone-driving mechanism is controlled by the size of the beam as the yarn is wound thereon.

I have only shown in the drawings detached portions of a tapestry-setting frame with my improvements in cone-driving and speedregulating mechanism combined therewith sufficient to enable those skilled in the art to understand the construction and'operation of the same.

Referring to the drawings, Figure 1 is a side view of parts of a tapestry-setting frame with my improvements applied thereto looking in the direction of arrow a, Fig. 2. Fig. 2 is a front view of the parts shown in Fig. 1 looking in the direction of arrow b, same iigure. The lower part of the frame shown at the left in Fig. 1 is broken away. Fig. Sis a section on line 3 3 Fig. 2, looking in the direction of arrow c, same figure, and showing some of the parts which are broken away in said figure; and Fig. 4 is a section on line 4 4, Fig. 3, looking in the direction of arrow d, same figure. The broken lines indicate the warp on the warp-beam.

In the accompanying drawings, 1 is one of the side frames or ends -of a tapestry-setting frame 2, a cross bar or brace secured to the upper part of the frame 1 and connecting it to the other side frame. (Not shown.)

3 is a belt-pulley driven by a belt (not shown) and fast on the shaft 4, journaled in suitable bearings and having fast thereon the lower cone 5. The shaft 4, carrying the beltpulley 3 and cone 5, has a continuous rotary' motion and is mounted in a swinging or pivotally-supported frame 6, which is supported and swings in journals at each end, having bearings on the frame or some stationary part of the machine. One journal 6 is shown in section in Fig. 2. A lever 7 is secured to or made a part of the frame 6 at one end thereof, at the front of the machine (see Fig. 2) and has a slot 7 in its upper end, into which eX- tends a pin 8 on a handle 8, pivoted at 9' on a bracket 9, secured to the end frame of the machine. (See Fig. 1.)

By means of the lever 7, through the raising of the handle 8, as indicated by broken lines in Fig. 2, the frame 6 is raised on its pivotal supports, and the lower cone 5, around which loosely passes the endless belt 10, is raised with it to bring the belt 10 into contact with the upper cone 11, causing it to rotate in the usual way. (See Fig. 4.)

The upper cone 11 extends above the cone 5 and is oppositely arranged and is fast on a shaft 12, mounted in suitable bearings 13 on the end frame 1. (See Fig. 1.) On the shaft 12 is fast a worm 14, which meshes with and operates a worm-gear 15, which is loosely mounted on the outer end of a shaft 16 and carries a pawl 17, which is adapted to engage a ratchet-wheel 18, fast on the shaft 16- to turn the shaft. The shaft 16 is in this instance of square shape transversely through its central part and carries thereon the warpbeam 19 for the printed yarn.

I will now describe the means for automatically controlling the movement of the endless belt 10 in the direction of the length of the cones 5 and 1 1 to regulate the speed of rotation of the warp-beam 19, according to the amount of yarn wound thereon. The endless belt 10 extends between the ends of a sliding fork 20, (see Fig. 4,) mounted and adapted to slide on a square rod 21, supported behind the cones 5 and 11. (See Figs. 3 and 4.) The fork 20 has a pin 20 thereon, (see Fig. 4,) which is connected with a chain roo l 22, which ,passes over a guide-sheave 23 on the end frame 1 (see Fig. 3) and over a second guide-sheave 24 on a stud 24 on the end frame 1 and is attached to an arm 25, the hub 25 of which is fast on a square-shaped rocking shaft 26, mounted in suitable bearings on the end frames of the machine. (See Fig. 2.) The chain 22 extends from the pin 20 on the fork in an opposite direction over, in this instance, a guide-sheave 27 on a pin 27 on the end frame 1 and a second guide-sheave 28 on a pin 28 and is attached to one end of a spiral expansion-spring 29. The other end of said spring 29 is attached to the arm 25. (See Fig. 3.) The rocking of the shaft 26 to mo ve the arm and, through the chain 22, to move the fork 20, and consequently the belt 10, is caused by the mo vement of a lever 30, the

. hub 30 of which is fast on the shaft 26. The

lever 30 has a weight 30 adjustable thereon at one end and carries in this instance two rolls 31 at its other end, which support the hollow pressure-roll 32, which bears against the periphery of the printed yarn on the warp-bea1n. (See broken lines in Fig. 3.)

The operation of my improvements will be readily understood by those skilled in the art from the above description in connection with the drawings.

When the machine is not in operation, the lower cone 5 is in its lowered position, supported on the swinging frame 6, which is also in its lowered position. To operate the machine, power having been applied to the beltpulley 3, the handle 8 is raised to mo ve in the upper end of the lever 7, as shown by broken lines in Fig. 2, and move the frame 6 on its pivotal supports to raise the cone 5, and with it the endless belt 10, to bring the belt into engagement with the cone 11 to rotate said cone and, through intermediate connections, (shown 1n Fig. 1,) rotate the warp-beam 19 on the shaft 16.

When the yarn begins to be wound on the beam, the weighted end of the lever 30 will be in its lowest position and the endless belt 10 at the large end of the driving-cone 5.

The spring 29 expands as the arm 25 moves up with the rocking of the shaft 26 through the movement of the lever 30, caused by the pressure-roll 32 being in engagement with the yarn on the warp-beam, and allows the belt 10 to remain in the same position between the two cones 5 and 11 when the cones are pressed together-that is, when the machine is started one stretch of printed yarn, which will run from ten to twenty feet in length, is wound on the beam, and the belt 10 by the expansion of the spring 29 will remain in the same position, as 1t requires more power to move the belt 10 than to expand the spring 29.

After one stretch of printed y arn-from ten to twenty yards-are wound on the warpbeam; then the handle 8 is moved down to lower the frame 6 and the driving-cone 5, and

the tension on the belt 10 between the two cones 5 and 11 being removed the belt will be moved along between the two cones by the movement of the chain 22 and fork 2O on the contraction of the spring 29 to take a position nearer the small end of the driving-cone i 5. The handle 8 is then raised to move up the cone 5 and bring the belt 1() in engagement with the cone 11 to rotate the same and the warp-beam to wind another stretch of yarn thereon, and this operation is repeated until the warp-beam is filled.

It will be seen that the speed of revolution of the warp-beam is automatically regulated by the amount of yarn on the beam through the automaticmovement of the endless belt 20. I prefer to use a spring 29 for the purpose above described; but, if preferred, the spring may be dispensed with, and then the belt 10 will be automatically moved between the cones 5 and 11 in the direction of their length by the movement of the chain 22 and fork 20, through the rotation of the shaft 26, carrying the arm 25 and the lever 30.

It` will be understood that the details of construction of my improvements may be varied, if desired, and their use is not necessarily limited to a tapestry-setting machine.

I have shown in the drawings and described herein the endless belt 10 passing around the lower cone 5, the bearings of which are mounted in the pivotally supported or swinging frame 6, and I prefer this construction; but the endless belt 10 may pass around or encircle the upper cone 11, if preferred.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a tapestry-setting machine, the combination with the beam on which the warp is wound, of a cone-driving mechanism for said beam, comprising connections to a rotary shaft having stationary bearings, and said shaft, a cone fast thereon, a second cone fast on a shaft having bearings on a swinging or pivotally-supported frame, and said shaft and frame, and means to move said frame, and a belt encircling one of said cones, and movable inthe direction of the length of the cones.
